SEECIFICATION iormingpart of Letters Patent No. 295,891, dated March 25, 1884:.

Application filed November 15, 1883. (No model.)

To a whom, it may concern: V

Be it known that I; BENJAMIN WEBSTER, a citizen of Great Britain, residing at Bridgeport, in the county of Fairfieldand State of' Connecticut, have invented certain new and useful Improvements in Feed-Water Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the at no time is there any steam in the hot-water reservoir; and with these ends in view my invention consists in the details of construction and combination of elements hereinafter fully and in detail explained, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may more fully understand the construction and operation of my improvement, I will proceed to describe the 0 same in detail, referring by letters to the accompanying drawing, forming a part of this specification, in which is shown a central vertical section of a feed-water heater embodying my improvement.

3 5 .A isthe reservoir, constructed with its upper portion narrowed, so as to form a neck, B. G is the water-inlet pipe leading into said neck l at the side thereof, and D the exhaust-steaminlet pipe led into said neck at the top and in a plane at right angles to that of the water-inlet pipe. The diameter of said exhaust-pipe is such that a narrow chamber, E, is left between said pipe and the wall of the neck B, which forms a receptacle for the water as it comes from the pipe 0. The pipe D, where it enters the neck, is packed in any ordinary way to prevent any escapement of ,the water..

, Theinner wall of the-neck meets the casing of the reservoir proper at a right angle, as clearly Shown at F, and the pipe 1) extends within the neck, so as to leave only a narrow Space between the pipe itself and said casing, so that it will be readily understood that the waterexit G extends horizontally-or in a plane at right angles to the direction of the flow of the exha11st-steam. As the water flows into the neck B it is discharged in a sheet extending horizontally across the opening where the neck joins the reservoir. The flow of the steam is blocked completely by this sheet, which -not 6o only causes an. absolutely perfect condensation, but also a uniform, constant, and thorough heating of the water, and the latter drops or flows down into the reservoir, as clearly shown. videanymeansforadjustingtheexhaust-steaminlet pipe in order to regulate the size of the water-exit, this may be readily accomplished in any well-known way; also the filow of water may be regulated in any manner desired. 7o

Prior to my invention various devices of this description have been constructed; but in none of these has the condensation been perfeet, and therefore the water is not heated uniformly and a great body of steam is wasted,

which of course necessitates the use of an exhaust-pipe. My improved heater may be used in connection with injectors by simply putting a valve into the exhaust-inlet pipe, giving the water at 140 temperature to the injector. So

In some cases it is desirable to make substitutes for expensive steam-traps by leading drips from coils into the heater from upper rooms, thus utilizing what would otherwise be a nuisance. plished by means of my improved heater.

By the use of my improvement the steam power of the boiler is greatly increased, the effect being equal to the addition of at least one-eighth (t) to the heating-surface, thus producing an ample supply of steam without heavy firing. The condensation in the heater of so large a quantity of waste steam reduces the back-pressure entirely, and to that extent increases the power of the engine. The heater is easily fixed .to any steam or plunger pump, and is preferably cast in one piece and tapped for ordinary pipe-fittings.

Should it become necessary to pro- 65 This can be readily accom- 85.

5 with the exhaust-steam-inlet pipe, of the water-exit arranged at right angles to said pipe, substantially as set forth.

2. In a feed-water heater, the water-chamber constructed with a rectangular lower por- 10 tion, in combination with the steam-inlet pipe extending downward at right angles to said portion and forming the upper wall thereof, substantially as described.

3. In a feed-water heater, the combination,

with the neck or upper portion of the reservoir, of the steam-inlet pipe extending within said portion in such manner that a water-chamber is formed whose exit is at right angles to said pipe, whereby the water is discharged in a sheet directly across the current of the steam, substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

BENJAMIN WEBSTER.
